What is what do you need to know when passing under a bridge?

When passing under a bridge, you need to be aware of several important factors:

• Vertical Clearance: This is the most crucial aspect. Ensure your vehicle or vessel's height is less than the bridge's posted clearance. Exceeding the clearance can lead to a collision, causing significant damage and potential injury. Always check for signage indicating the clearance height, and if unsure, err on the side of caution.

• Water Level: For boats and other watercraft, fluctuating water levels can significantly reduce the available clearance under a bridge. Consult tide charts or local information to determine the current water level and calculate the actual clearance.

• Bridge Condition: While not always apparent, bridges can have structural issues. Be aware of any visible signs of damage or deterioration, such as cracks, rust, or missing pieces, and report any concerns to the appropriate authorities.

• Traffic Conditions: Bridges can be bottlenecks, especially during peak hours. Be mindful of traffic flow and potential congestion before entering a bridge underpass.

• Navigation Aids: For maritime navigation, pay close attention to any buoys, lights, or other navigational aids that mark the safe passage under the bridge. These aids provide critical information about the channel and potential hazards.

• Local Regulations: Some bridges may have specific regulations or restrictions, such as speed limits, weight limits, or restrictions on certain types of vehicles or vessels. Be sure to familiarize yourself with any applicable local rules before passing under the bridge.
